converter charger

This converter charger converts AC shore power into DC power and charges your battery bank. The converter uses a high voltage output to provide the proper charging profile for lithium batteries. If your RV already has a stock converter charger, it will need to be removed to ensure this unit operates properly.

Designed for Lithium Batteries

Built for lithium batteries, this unit uses a higher output voltage than a typical converter charger, which provides a fast, complete charge. The charger also extends battery life since it utilizes the appropriate charging profile. Additionally, it's compatible with your battery's internal Battery Management System (BMS), which helps manage charging by monitoring the battery state and balancing cell voltage.

Parallel and Series Capability

If your battery bank requires a higher amperage or voltage to charge properly, you can connect identical converter chargers together to accommodate your setup. With parallel wiring, you can increase the charging current which is useful for high-capacity battery banks. Conversely, you can wire them in series, which increases the voltage so you can charge 24V, 36V, or 48V systems.

Safety Features

cooling fan

The system includes a number of safety features. It has a reverse polarity protection that will protect the converter if the battery is hooked up incorrectly. It has short circuit protection as well, which limits the current and reduces the output until the short has been fixed. Additionally, the converter will shut down if there is excessive voltage. The built-in cooling fan also removes excess heat from the unit and only operates during high loads.

How It Installs

The converter mounts horizontally inside your RV in a dry location with ventilation. However, as long as the unit has sufficient ventilation, it can also be mounted vertically. The mounting hardware is not included.

terminals and plug

The DC output terminals wire to the battery bank. The AC in cord plugs into a 120V 3-wire grounded outlet.

As always, great service and on time de livery.


Easy to install and has been working flawlessly for us for several months. We use it so we can charge our off grid 24 volt lithium battery bank with the generator when it has been to cloudy for the solar panels to keep up.




etrailer should take some lessons from Amazon. When multiple products are sent to a distributor in a large box or pallet, the individual items should then be shipped for an order in a secure package. etrailer simply slapped a label on the manufacturer’s flimsy carton and tossed it to USPS who succeeded it breaking the single stran of tape around the box. When I received the package, the box was totally opened on one end and the inverter mounting tab was bent. Not the delivery I would expect for a $600+ item.


We utilized the Progressive Dynamics Inteli-Power RV Converter and lithium Battery Charger as part of our lead acid to Lithium upgrade for our Aliner RV. We had several manufacturers to choose from but are very pleased with our decision to go with this product. It’s performance remains steadfast after the first year in service, its quiet, efficient, reliable and perhaps best of all MADE IN AMERICA! The multi stage smart charging g work flawlessly with our Lithium battery system. 100% recommendations from this satisfied us timer!


I installed this in my camp with 400 watts of solar an a LFP04 battery with a generator hookup. I use the lithium charge profile and it works great. It runs my 12v rv refrigerator with no issue.


Installation of PD9260C into Parallax 7300 power distribution panel

I purchased the Progressive Dynamics PD9260 to replace the power converter in my 2007 Airstream. My trailer had a Parallax7300 power distribution and power converter (AC to DC) installed from Airstream. I decided to replace just the power converter after it had failed. The PD9260C fit perfectly where the previous converter was installed with very little modification or effort.

I simply removed the older converter, removed some standoffs where the previous converters circuit board was mounted along with the old fan, and then drilled some holes to mount the PD9260 in the mounting tray of the old unit. I wired the new converter to the existing connections and tried it out. Everything worked as expected.


A little bit confusing when speaking with sale team, received conflicting information regarding converters application. Shipping was fast but converter container was damaged and poorly packed for sensitive electronics. Previous business with etrailer has been stellar. May be awhile before I can hookup converter, so hopeful nothing was damaged!


I purchased the Progressive Dynamics PD9200 to replace a failing OEM converter. The unit is wider than the original but with some minor wood work I was able to install it in the original location. As soon as I powered it up all of our problems in the 2018 Forest River 5th wheel vanished. Our main issue was flickering LEDs which drove us crazy. Time will tell if this is a quality product. etrailer is amazing to work with. The item arrived ahead of the estimated delivery date. It was packaged in the original box so the serial number on the unit matched the number on the box. No fear of counterfeit items from these folks.


Glad I went lithium. Actually I have both. I can flip between lithium and my lead acid batteries for cold weather travels. But lithium charges up in half the time or less. And I have almost twice the reserve power. My only question for myself is, do I go solar, or do I install another bank of lithium? By far this is the best upgrade I've made to our rig.


Game-changer for our lifepo4 batteries! I swapped out the PD 4135K for the WFCO 8735P that came standard in our trailer. Installation was fairly easy, just had to glue and screw a 1/2" square dowel in one side of the cutout to make the opening smaller. Wiring was simple. We only charge throu the converter when we don't have enough solar, and it's nice to know we're maximizing the charging from our generator. The lithium switch is really small and a little hard to access, but I shouldn't need to get to it again unless we switch back to AGM, which isn't going to happen. Happy we made the change!


I used this to replace a WFCO 9855 AD. The autodetect in the WFCO rarely worked properly. This Progressive Dynamics unit has been so much simpler and better for my batteries. I have (2) 200 ah Lifepo4 batteries. I finally got them to 100% charge. I was torn between the 45 amp and the 60 amp version. I ultimately chose the 45 amp to keep my amps down when plugged into lower amp shore power and also didn't want to stress the batterie cables.

My only minor complaint is the high power charging only lasts about 8 or 10 hours, before kicking to a maintenance charge. I have to disconnect wait 10 minutes and reconnect the converter to restart the high power charging cycle.


This is working well for us in our diy camper! We had to use [online] to figure out how to hook it up.


I always get my battery chargers manufactured by Progessive Dynamics ( no matter what battery tech I use). Never had a failure in 10 plus years!


This all-in-one power center is very well designed. Made to keep on-board batteries continuously charged, plenty of room for branch circuit breakers and 12v circuits. Built-in ventilation fan to keep the electronics cool. It comes in a smart looking case with hinged door access to the breakers and fuses and led indicator lights showing blown fuse location. Vey pleased with my choice of a distribution center for my trailer rebuild.


It’s good to get my 5th wheel trailers charging system working again. It took extra time to receive the inverter do to out of stock but the unit works perfectly and my batteries are charging properly.


When my 40-amp converter suddenly quit working, I began searching for a replacement after confirming with my multimeter that there was no output. I found very few 40-amp and those were very $$$. I contacted to see if I could replace with a 45-amp. A quick response assured me it would assuming the 12v wiring would be heavy enough since an additional 5-amps would be minimal. The installation was very simple, and the system was immediately restored.
THANKS, etrailer!!


First off a big 'Thank You' to etrailer for sending it two-day shipping even though I had free shipping. You won't get that at [online]! Item arrived in perfect shape. Easily installed and worked as soon as I turned it on. Will shop etrailer again!


Very concerned about this. Unit arrived via USPS in an unmarked cardboard box with zero packing. There was at least of clearance on sides which means it was banging around in the box the whole trip. Looks like a return. No hardware, or screws included. It wasn't even in a bag and "manual" is a corner-stapled 8.5x11 photocopy.

I wasn't planning on installing this right away, and now I'm thinking about returning because I don't want to have problems down the line due to unseen damage or broken solder joints. Very sketchy.


Only downside to the unit is the installation documentation. It’s not as clearly explained to the first time DIY installer. Had to resort to YouTube videos to complete installation. It would be nice to have a step by step tutorial video made by PD or eTrailer for installation purposes. Otherwise, unit is working great and as intended.


Purchased this inverter for sole reason to run my new RV 120v a/c refrigerator. I recommend the remote panel, easy off/on as well battery voltage indicator. The existing circuit I used for refrigerator also was for a few receptacles, handy to have for cellular WiFi router while under way. Has been a year now, no regrets, I like it.


This has made huge difference when dry camping with our rv. I added solar panels and three 100 amp hr batteries along with this inverter. Coffee, microwave, and yes the wife's blow dryer works flawlessly. No need to put my boots on and go start the generator.
I don't have the AC wired to operate off the inverter, nor would it work.
All positive feed back from me.
What I know now;
1) It can't be mounted near flammable fuel tanks.
2) You must use correct size wire with proper connections.
3) Mount the unit as close as possible to the batteries because the battery cable (200 amps) are more expensive than the line voltage wire (15 amps).
4) The remote panel comes with a long cord to mount inside anywhere.


The item I ordered was perfect for my trailer setup. 1 unit housing distribution panel and converter. Installation was very easy, however, instructions for wiring could be better. I used a Google video to verify wiring. Haven't used the item yet but I suspect it will be great for my trailer.


Works better than expected. It was a nice upgrade to my 1988 Toyota Odyssey Motorhome.The original one had failed. The new one is much better as I don't need worry about overcharging and drying out the battery.Installation was easy too with the instructions.
